From the report:
It was also noted that, in the absence of autopilot or continuous manual control, an aircraft is very unlikely to maintain straight and level flight. Further, it is extremely unlikely for an aircraft to enter and maintain a turn and then return to straight and level flight for any significant period of time.
From the foregoing discussion it can be generally deduced that there is no evidence to suggest that a malfunction had caused the aircraft to divert from its filed flight plan route.
The analysis of the relevant aircraft systems taking into account the route followed by the aircraft and the height at which it flew, constrained by its performance and range capability, does not suggest a mechanical problem with the aircraft.
Yes, there will always be some element of uncertainty as there were no survivors and no FDRs recovered. However, when you have pretty much proven to yourself that the aircraft was deliberately flown to wherever it crashed, I’d have thought at least a suggestion of “unlawful interference” could be made, as opposed to:
In conclusion, the Team is unable to determine the real cause for the disappearance of MH370.
Which is a bit of a cop-out, IMHO.
